Extract firmware from printer.

Hi all, I donít really know if this is a programming question or if I am asking on the right board. But I wanted to know if any one knew if it was possible to extract the firmware from a printer (a Dymo Labelwriter 400) then copy it back to an identical printer, well one with an outdated firmware.

If you have enough resources [money/time] you can extract firmware from anything - but in this case, I suspect it's not worth the effort for a single printer.

It is unlikely that the printer has a function that allows SOFTWARE to read out the firmware - why would you ever need that? So why would someone put the code in the driver/printer to perform such a task [I'm not saying it can't be done, but there's really no "use case" for this sort of functionality]. There is probably a way to update the printers firmware, with the right software, but to "upload from printer to host computer" has no meaning - the use-case is that you have an upgrade in the host-computer, and download into the printer. You get such updates from the producer of the printer.

try to find teh EPROM chip on the printer circuitboard. it should have a number like 27c010 or similar, it will start with 27, maybe like MCM27c etc. Thats the firmware. Now buy an identical chip and use an eprom burner to copy it.

Until you can build a working general purpose reprogrammable computer out of basic components from radio shack, you are not fit to call yourself a programmer in my presence. This is cwhizard, signing off.
